Tools & capabilities

Hash tools 2

  • hashCompute a cryptographic hash (hex digest) of text: algorithm = md5, sha1, sha256 (default), sha384, or sha512. Keyless/offline; the input is not stored or transmitted. MD5/SHA-1 are legacy (checksums only, not security).
  • hmacCompute an HMAC (hex) of text with a secret key. algorithm = sha1, sha256 (default), sha384, or sha512. Keyless/offline.

Agent Passport System — Cryptographic Identity for AI Agents tools 154

  • list_profilesShow available tool profiles. Set APS_PROFILE env var to limit exposed tools (e.g. APS_PROFILE=data).
  • list_tools_for_scopeList available MCP tools filtered by delegation scope. Pass your delegation scopes to see which tools you can use. Scopes: identity, delegation, principal, reputation, coordination, communication, governance, commerce, data, gateway, network, temporal, attribution, settlement, capability, mutual-auth. Use ['*'] for all tools.
  • identifyIdentify yourself to the coordination server. Sets your role and scopes tools accordingly.
  • generate_keysGenerate an Ed25519 keypair for agent identity.
  • issue_passportIssue a complete agent passport with keys, signed passport, attestation summary, and optional values floor in a single call. The server silently captures Tier 0 observed signals and computes a passport grade (0-3). Use this to onboard any agent without an npm install.
  • verify_issuerVerify that a passport was officially issued by AEOESS. Checks the issuer countersignature against the published AEOESS public key. Returns false for self-signed passports.
  • get_passport_gradeQuery the attestation grade and issuance context for a passport. Returns the passport grade (0-3), flags, and evidence summary. Grade 0 = self-signed, 1 = issuer countersigned, 2 = runtime-bound, 3 = principal-bound. This is the partner-facing trust query.
  • list_issuance_recordsList all stored issuance records with their passport grades. Shows how many passports have been issued in this session and their trust posture. Useful for monitoring issuance patterns.
  • get_behavioral_sequenceGet the post-issuance behavioral sequence for an agent. Shows the first 10 tool calls after passport issuance. Real agents do work. Farming agents extract.
  • get_my_roleGet your current role, assigned tasks, and role-specific instructions.
  • create_task_brief[OPERATOR] Create a new task with roles, deliverables, and acceptance criteria.
  • assign_agent[OPERATOR] Assign an agent to a role in a task. Creates a delegation automatically.
